The proposed action consists of a minor discharge of fill required for streambed stabilization needed to protect of an existing petroleum pipeline located within CPC's maintained right-of--way (ROW). The proposed activity will require minor disturbance to Park Creek in Rowan County, North Carolina, at 35° 30.902"Nand 80° 42.445" W (Figure i). Background CPC's above referenced maintained ROW, contains two pipelines that transport refined petroleum: Line 1, 4o-inch diameter; Line 2, 36-inch diameter. At the above referenced site, bank erosion and streambed degradation has exposed Line i within the stream channel, significantly reducing the required cover protection level of the pipeline.

Soo Fax: 770-591-9993 Woodstock, Ceorgiu ,3oi8S www.wet-eco.com PCNNWPNo. i8 July i9, 2ooy Colonial Pipeline Company -Park Creek WECProject No. o2-o4i9o~ Proposed Activity in Waters of the U.S. The minor discharge of fill will require disturbance to approximately ~o linear feet of Park Creek to stabilize the stream bank and protect the existing pipeline. The pipeline will be protected using pre-cast concrete revetment mats placed into a 45-linear foot segment of the stream channel (Appendix A). CPC will also place riprap into an additional 25 linear feet of the stream (i.e., ~o linear feet total) below the ordinary high water mark. The quantity of this "fill material" (i.e., revetment mat and riprap) below the plane of the ordinary high water mark will be less than 22 cubic yards. To minimize sedimentation to the creek during the activity, temporary dams will be constructed at each end of the work area and the stream flow will be pumped around the area. The dams will be constructed of sandbags or other suitable material, and the pump capacity will be able to sufficiently accommodate the stream flow. The pumps will be installed above the upstream dam with the discharge line routed through the disturbed area, discharging immediately downstream of the downstream dam (Appendix B). As an alternative method to using a pump, CPC may use a steel pipe flume to convey the stream flow through the reach of stream to be disturbed. The flume will be used to maintain flow to the downstream side of the disturbed area, and the excavation will be carried out under the flume (Appendix C). Both techniques allow the maintenance to take place without contact to flowing water (i.e., "in the dry"), thus reducing downstream sedimentation. To prevent future erosion of the streambed at this location, and to protect the pipeline from damage, pre-cast concrete revetment mats will be used to cover and protect the pipeline while stabilizing the adjacent segments of the streambed as depicted in Appendix A. The revetment mats will extend approximately 45 linear feet within the stream channel. The reshaped stream bank will be stabilized with geotextile erosion control mats, and CPC's Soil Erosion and Sedimentation Control Plan will be implemented to protect the stream from sedimentation (Appendix D). Nationwide Permit General Conditions Summary We have provided the following information to document compliance with the USACE NWP general conditions. Each condition and subcategory is itemized below. 2 PCNNWPNo. i8 July ~g, 200 Colonial Pipeline Company -Park Creek WECProjectNo. o2-o4i9oi General Condition i -Navigation The project site does not occur within navigable waters. General Condition 2 -Aquatic Life Movements The discharge of fill activity within the stream will be minimal. The revetment mats will be "keyed" into the streambed, and will not impede the passage of normal stream flow or aquatic life. General Condition ~ -Spawning Areas Not applicable. General Condition 4 -Migratory Bird Breeding Areas Not applicable General Condition ~ -Shellfish Beds Not applicable General Condition 6 -Suitable Material The concrete revetment mats are pre-cast and hardened before they are placed in the stream. General Condition ~ -Water Supply Intakes The proposed construction does not include a water supply intake. General Condition 8 -Adverse Effects from Impoundments Not applicable. General Condition 9 -Management of Water Flows During the proposed activity, water flows will be maintained by the use of either a dam and pump system (Appendix B) or a flume used to convey the flow of the stream (Appendix C). The concrete revetment mats will be "keyed" in to the upstream end of the disturbed area to prevent impediment of streamflow (Appendix A). General Condition io -Fills Within ioo-Year Floodplains The project will not result in above grade fill placed within the ioo-year floodplain. General Condition ii -Equipment Equipment will be operated from the stream banks. 3 PCNNWPNo. ~8 July i9, 2ooy Colonial Pipeline Company -Park Creek WECProjectNo. o2-o4i9oi General Condition 12 -Soil Erosion and Sediment Controls Best Management Practices and proper erosion and sedimentation controls will be followed during the maintenance activity (Appendix D). General Condition i~ -Removal of Temporary Fills All temporary water flow diversion devices will be removed immediately following the maintenance activity. General Condition i4 -Proper Maintenance The existing pipelines and ROW will continue to be maintained and inspected on a regular basis to ensure public safety. General Condition i~ -Wild and Scenic Rivers The project site is not located in or adjacent to a Wild and Scenic River. General Condition i6 -Tribal Rights The project site is not located within or adjacent to an Indian reservation or nation. General Condition i~ -Endangered Species No impacts to federally protected species are expected from this project. According to current North Carolina Natural Heritage Program data, the only federally protected species listed to occur in Rowan County are the bald eagle (Haliaeetus leucocephalus) and Schweinitz's sunflower (Helianthus schweinitzit~. At the project location, neither species were observed at the time of the site visit. Further, this area does not provide suitable habitat for bald eagles or the sunflower due to the routine maintenance of the ROW (i.e., mowing). General Condition i8 -Historic Properties The proposed activity will be conducted within the existing pipeline ROW, which has been previously disturbed; thus no archeological resource impacts are probable. No historic structures were noted within the project area, and no aboveground structures are proposed for construction. Therefore, the proposed pipeline protection activity will have no adverse affects to cultural resources in the project vicinity. General Condition 1g -Designated Critical Resources Waters Not applicable. General Condition 20 -Mitigation The proposed pipeline protection activities have been designed to avoid and minimize impacts to jurisdictional waters to the maximum extent practicable. The stream disturbance of approximately ~o linear feet does not exceed any of the USACE, Wilmington District, Nationwide Permit Regional Conditions requiring mitigation [Refer to USACE, Wilmington District Regional Condition 3 (2) below]. However, the proposed stream/bank stabilization completed to maintain and 4 PCNNWPNo. ~8 Colonial Pipeline Company -Park Creek July i9, 2ooy WECProjectNo. o2-o4igoi protect the existing pipelines will result in improved water quality of the stream by reducing soil/bank erosion, which offsets the minor/temporary disturbance. General Condition 21 -Water Quality The activity will be in accordance with the conditions of the DWQ General Certifications for NWP 3 (WQC N0.3494) and NWP i8 (WQC No. 3402).

List of Final Corps Regional Modifications and Conditions for All Nationwide Permits: 1) NWPs may not be used for activities that may result in the loss or degradation of greater than goo total linear feet of perennial, intermittent, or ephemeral streams that exhibits important aquatic function(s). Loss of stream includes the linear feet of stream bed that is filled, excavated, or flooded by the proposed activity. The use of NWP i8 will result in less than 300 linear feet of disturbance to the streambed. 2) For any NWP that results in impacts more than lso total linear feet of perennial and/or ephemeral/intermittent stream, the applicant shall provide a mitigation plan to compensate for the loss of aquatic function, associated with the proposed activity. For stream impacts of less than iso linear feet compensatory mitigation is determined on a case by case basis. Stream impacts are less than iso linear feet, and the proposed pipeline protection activity will improve water quality and the aquatic environment by reducing bank erosion and stream turbidity. 3) For any NWP that results in a loss of more than iso linear feet of perennial and/or intermittent/ephemeral stream, the applicant must comply with NWP General Condition 2'J (PCN). Not applicable (i.e., less than iso linear feet of stream); however, a PCN is required for NWP i8 and compliance with NWP General Condition No. 2~ has been provided by the submission of this PCN. 4) For all NWPs which allow the use of concrete as a building material, measures will be taken to prevent live or fresh concrete, 6 PCNNWPNo. ~8 Colonial Pipeline Company -Park Creek July ig, 200 WECProjectNo. o2-ogl9oi including bags of uncured concrete from coming into contact with waters of the state until the concrete has hardened. The concrete revetment mats that will be used to stabilize the streambed and protect the pipelines from future exposures are pre-cast and hardened before they are placed in the stream. 5) For all Nationwide Permits that allow for the use of riprap material for bank stabilization i) Filter cloth must be placed underneath the riprap as an additional requirement of its use in North Carolina waters. The riprap will be placed on a geotextile fabric in the stream. 2) The placement of riprap shall be limited to areas depicted on submitted work plan drawings. Riprap will be limited to the area indicated on Appendix A. 3) The riprap material shall be clean and free from loose dirt or any pollutant except in trace quantities that would not have an adverse environmental effect. The riprap will be clean/free of dirt. 4) It shall be of a size sufficient to prevent its movement from the authorized alignment by natural forces under normal conditions. The riprap will be of sufficient size to prevent movement downstream. 5) The riprap material shall consist of clean rock or masonry material such as, but not limited to, granite, marl, or broken concrete. The riprap materials used will consist of clean rock or masonry material. 6) A waiver from the specifications in this Regional Condition maybe requested in writing. The waiver will only be issued if it can be demonstrated that the impacts of complying with this Regional condition would result in greater adverse impacts to the aquatic environment. Not applicable. 6) For all NWPs that involve the construction of culverts, measure will be included in the construction that will promote the safe passage of fish and aquatic organisms. The dimension, pattern, and profile of the stream above and below a pipe or culvert should 7 PCNNWPNo. i8 Colonial Pipeline Company -Park Creek July 19, 2007 WEC Project No. o2-oqi 9oi not be modified by widening the stream channel or by reducing the depth of the stream in connection with the construction activity. The width, height, and gradient of a prposed opening should be such as to pass the average historical low flow and spring flow without adversely altering flow velocity. Spring flow should be determined from gage data, if available. In absence of such data, bankfull flow can be used as a comparable level. Not applicable. ~) Applicants shall notify the NCDENR Shellfish Sanitation Section prior to dredging in or removing sediment from an area closed to shell fishing where the effluent maybe released to an area open for shell fishing or swimming in order to avoid contamination of the disposal area and allow a temporary shellfish closure to be made. Any disposal of sand to the beach should occur between November 1 and April 3o when recreational usage is low. Only clean sand should be used and no dredged sand from closed shell fishing areas. If beach disposal was to occur at times other than stated above or if sand from a closed shell fishing area is to be used, a swim advisory shall be posted, and a press release shall be made. Not applicable. 8) Adverse impacts to Submerged Aquatic Vegetation are not authorized by any NWP within any of the 20 costal counties. Not applicable. 4.

Description This section defines the soil erosion and sediment control measures that Colonial Pipeline Company will implement during and after inspection and repairs of the pipeline are complete. The objectives of this plan are to establish general guidelines for controlling erosion and sedimentation and to specify criteria for sensitive or particularly susceptible soil areas. The plan incorporates measures to control erosion and sedimentation, including minimizing cover removal, limiting the time of exposure, limiting the flow of water onto the disturbed right-of-way, and filtering or settling out sediment from water flowing from the right-of--way. The primary objective of the soil erosion and sediment control plan is to reduce the area and duration of soil disturbance and reestablish permanent vegetation as soon after construction as possible, thereby minimizing long-term erosion and sedimentation. Some erosion is inevitable during construction; however, the plan includes measures to reduce erosion to the minimum practical. Colonial Pipeline Company plans to reduce soil erosion and provide sediment control during the repair of the pipeline at the project site by incorporating the following measures: • Water pumped from the construction area as part of the dewatering operation from the excavation will be filtered through silt filtration bags and discharged to awell-vegetated area. • All work will be confined within the existing right-of--way. Staked hay bales and silt fence will be installed around the worksite and maintained until vegetation is established. Proper controls will be added if necessary during construction. • All terms and conditions within Nationwide Permit 3 will be followed. • Erosion control measures will be installed prior to conducting any soil disturbing activities associated with the pipeline maintenance activity. 1 of 2 • Clearing of vegetation will be kept to an absolute minimum and confined to the existing pipeline easement area. The easement area is 6o feet in width and devoid of large trees. The right of way is vegetated with undergrowth grasses and other short vegetation. • Vegetation will be reestablished within disturbed areas and along stream banks as soon as possible upon completion of work. Disturbed areas will be seeded with a native seed mixture • All erosion and sediment control measures will be inspected every two weeks at a minimum and after every significant rainfall event of o.5 inch or more until disturbed areas have been stabilized. Identified damages to control measures must be repaired immediately. Refuse and Waste Disposal Colonial's representative will not allow the Contractor to discard any litter, including paper, bottles, cans, rags, sacks, welding rod stubs, fuel, crankcase draining, coating materials, equipment, and junk pipe in the ditch or along the right-of--way. All refuse must be collected and disposed in accordance with company specifications. Personnel will be instructed regarding the correct procedure for waste disposal. Maintenance/Inspection Procedures The following inspection and maintenance practices will be implemented to maintain erosion and sediment controls: i. All control measures will be inspected every two weeks at a minimum and following any storm event of o.5 inch or greater. 2. All control measures will be maintained in good working order. If a repair is necessary, it will be initiated within 24 hours of the report. 3. Built-up sediment will be removed from silt fences when it has reached one-third the height of the fence. 4. Silt fences will be inspected for depth of sediment, tears, secure attachment of the fabric to the fence posts, and firm placement of the fence posts in the ground. 5. Temporary and permanent seeding and planting will be inspected for bare spots, washouts, and healthy growth. 6. Colonial Pipeline Company will select individuals to be responsible for inspections, maintenance and repair activities, and completion of the inspection and maintenance report. Personnel selected for inspection and maintenance responsibilities will receive training from Colonial Pipeline Company or its representative. Personnel must be trained in all practices necessary for maintaining the erosion and sediment controls used on-site. 2 of 2 APPENDIX E APPROVED JURISDICATIONALbETERMINATION FORM APPROVED JURISDICTIONAL DETERMINATION FORM U.S. Army Corps of Engineers This form should be completed by following the instructions provided in Section IV of the JD Form Instructional Guidebook.

Explain: ~ Boxes checked below shall be supported by completing the appropriate sections in Section III below. Z For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapaaoshave been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are °`relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section IILD.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands it any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. if the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. 1.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs.

Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. The proposed project is desisrned to minimize impacts to jurisdictional waters as much as practicable. The revetment mat and riprap will only be used to protect CPC's existing_pipeline and to stabilize the stream bank that is significantly eroded. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. Updated 1 I / 1 /2005 Page 9 of 12 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2 0. enr.state.nc.us/ncwetlands/strmgide.html. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).
